In some parts of Paraguay timber grows in abundance; it is cut, and floated down the river to Buenos Ayres, not in rafts but in single trees. On another occasion a Peon was gambling with a Spanish corporal in the prison-yard, when a dispute arising, the latter drew his sword on his unarmed antagonist, and wounded him so severely in the arm, that he was obliged to undergo amputation the day following. It is usual for a Peon who has been fortunate at play, to go to Monte Video and clothe himself anew in the shop of a slop-seller. While the shopman is looking out the articles he calls for, he deliberately places his dollars on the counter, in separate piles, assigning each to its destined purpose. He then retires to a corner, and attires himself; an unfortunate comrade invariably attends him, who examines his cast clothes, and, if better than his own, puts them on. After passing a few days in idleness, he sets out on his return home, where he appears in his new dress. In the mines they have two methods of estimating the quantity produced: for example; Quatro Vintens, here mean four vintens of gold, which is equal to eight of copper; whereas, in Rio de Janeiro, the same expression implies four vintens of copper. The following are the results of some experiments which he did me the favor to make: White sewing-silk, put into an alcoholic solution only once, received a fine strong purple. Part of a skein of the same material, was put into a solution of potash, which produced a purple deeper in hue than the former. Cotton thread and worsted yarn, immersed only once in the same solution, produced very nearly the same colors. The part of a skein of silk died in the alcoholic solution was immersed in a solution of muriate of tin, which produced a beautiful lilac, approaching to dove-colored blue. The same substance died in a solution of potash, and immersed in a solution of muriate of tin, became a few shades darker, and rather more of a pink hue. These are not unfavorable results from a quantity so minute; and I feel confident that this substance may be rendered a very valuable article of trade. A few weeks ago, I received another sample of excellent lichen, very full of color, which I hope may be turned to some advantage. It is much to be desired that the very excellent work, written by Bryan Edwards, upon sugar making, and distilling rum, was introduced in Brazil. |
